MEAT MANGLE OR TENDERER.

Specification of Letters Patent.

Patented Oct. 19, 1909.

Application filed November 30, 1908. Serial No. 465,232.

T 0 all whom it may concern:

Be it known that I, CARRIE MOBRATNEY, a citizen of the United States,residing at Fort Dodge, in the county of Ford, State of Kansas, haveinvented certain new and useful Improvements in Meat Mang-les 'orTenderers; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

The invention relates to a meat mangle and more particularly tothe classof machines for treating meats to make the same tender.

The primary object of the invention is the provision of a meat mangle ortenderer comprising a frame structure formed of two sections hinged toeach other, a pair of rotatable rollers having roughened workingsurfaces, one of said rollers being held in close relation to the otherroller by a tensioning means, and means for rotating the rollers inunison and between which rollers is adapted to be passed a piece of meatsuch as a steak or the like, so that the tissues therein will be severedto make the steak tender.

A further object of the invention is the provision of a meat mangle ortenderer in which a pair of rollers are slidably mounted in aguide'frame, slidable journal bearings supporting the rollers in theframe, link connections between the journals of the rollers to separateone from the other upon the swinging of the upper section on its hingesto one side of the lower section, and tension means for holding therollers in close operative relation with respect to each other, so thatupon passing meat between the rollers, the latter will act thereupon tosever the tissues of the meat to make the same tender.

In the drawings, accompanying and forming a part of this specification,is illustrated the preferred form of embodiment of the invention, whichto enable those skilled in the art to practice the invention, will beset forth at length in the following description, while the novelty ofthe invention will be included in the claim succeeding said description.

In the drawings :Figure 1 is a front elevation of the invention. Fig. 2is a side elevation thereof. Fig. 3 is a top plan view with the uppersection moved upon its hinges to one side of the lower section. Fig. 4cis a vertical longitudinal sectional view. Fig. 5 is a sectional view onthe line 5 5) of Fig. 1. Fig. 6 is a side elevation with the uppersection of the frame swung to one side of the lower section.

Similar reference characters indicate cor responding parts throughoutthe several or bar 13, and the guide pieces of the upper section beingconnected by a cross beam or bar 14. To support the frame 8 in avertical position, there are provided outwardly diverging legs 15, whichlatter are connected to opposite edges of the lower section 10 of theframe.

Contained in the guide pieces 12 of the upper and lower sections 9 and10, respectively, are elongated openings or slots 16 -which are adaptedto aline with each other when the upper section 9 is in a closedposition or is swung upon its hinges into alinement with the guidepieces of the lower section of the frame. In opposite longitudinal wallsor sides of the openings or slots 16, are guide grooves 17 which latterare engaged by guide tonguesor flanges 18 formed on alining pairs ofjournal bearings 19 and 20, which latter pair of bearings support orreceive the journal ends 21 of a lower roller 22, which latter is heldor mounted in the lower section of the frame.

Mounted in the journal bearings 19 which are arranged in the uppersection 9, are the journal ends 23 of an upper roller 24 and looselyconnected to the journal ends 23 of this said upper roller are the upperends of coupling links 25, the opposite ends of which contain elongatedslots 26 receiving the journal ends 21 of the lower roller, and whichslots 26 permit the separation of spacing of the upper roller withrespect to the lower roller upon the swinging of the upper section 9 onits hinges to one side of the lower section.

On the working faces of therollers 22 and 24, respectively, are formedrows of teeth llU having blunt ends 27, which teeth of one roller coactwith the teeth of the other roller when the said rollers are held inclose relation to act upon meat passed therebetween to shred ordisintegrate the fibers of the meat for the purpose of making the samemore tender.

Mounted within the upper section 9 and having opposite ends contactingwith the bearings 20, is an upwardly bowed flat spring 28, which latteris supported below the cross bar l t and which spring is acted upon ortensioned by a regulating screw 29 threaded centrally in a verticalmanner in the cross bar 14, so as to adjust the close relation of therollers with respect to each other and to maintain the latter in theiradjusted position. However, it is obvious that should the meat contain abone, the said rollers will be free to separate from each other, due tothe mounting of the bow spring in the upper section of the frame.

Connected to the journal ends of the rollers, exteriorly of the frame 8,are double cogged gears or pinions 80 which are adapted to mesh witheach other when the upper section is closed upon the lower section, sothat rotary movement imparted to one roller will cause a like movementto be imparted to the other roller. Fixed to one journal end of theupper roller 24, is a manually operable crank handle 31, whereby rotarymotion can be imparted to the rollers at the will of the operator.

Pivoted to the upper section 2d are swinging catch members 32, thelatter being adapted to be brought into locked engagement with pins 33projecting from the lower section 12, so as to maintain the said uppersection in a closed position upon the lower section. The said catchmembers 32, when released, will permit the upper sec tion to be swung toone side of the lower section to separate or space apart the rollersmounted in the frame of the machine.

hat is claimed is A machine of the class described, C0111- prising aframe with hinged upper and lower sections containing slotted guides inopposite sides thereof, ball retaining cup bearings slidable in saidguides, upper and lower rollers rotatably journaled in the bearings,tension means acting upon bearings supporting the one roller to hold thesame in close yieldable relation to the other, means for regulating saidtension, spaced link connections between the rollers and having lowerclosed slots in which the lower roller is journaled and upper open slotsin which the upper roller is ournaled, the open slots being adapted tofree said upper roller upon raising the one section with respect to theother, teeth projecting from the working faces of the rollers, meansrotating the rollers in unison, and locking members holding one sectionclosed upon the other.

In testimony whereof, I aiiiX my signature, in presence of twowitnesses.
